ROBERT V. JONES, OF KANSAS CITY, MISSOURI, ASSIGNOR TO JOSEPH S. LOVERING WHAR- TON, WILLIAM S. HALLOWELL, AND JOHN C. JONES, COMPRISING A FIRM DOING BUSI- NESS AS HARRISON SAFETY BOILER WORKS, OF PHILADELPHIA, PENNSYLVANIA.

HEATER SYSTEM FOR LOGOMOTIVE SERVICE.

To all whom it may concern:

Be it known that I, ROBERT V. JONES, a citizen of the United States, and resident of and whose post-office address is 3745 Troost avenue, Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Heater Systems for Locomotive Service, of which the following is a specification, taken in connection with the accompanying drawings, which form a part thereof.

My invention comprehends a system where a feed water heater conserves the thermal value in available exhaust steam, for the purpose, among others, of furnishing hot water to stationary boiler plants, heating or drying systems or other various'purposes, and supplying storage tanks with hot water for use in washing, filling or testing locomotive boilers or various other purposes.

The objects of my invention are, among others, to provide effective, economical and easily regulated means for accomplishing the ends herein described.

In carrying my invention into effect I preferably employ a feed water heater of the open type, in combination with an elevated tank, a pump for supplying water thereto, a pump for feeding water to stationary boilers and a pump for furnishing locomotive boilers, or other points of use, with water at a given temperature under pressure, all of which are preferably arranged substantially as hereinafter described and, generally, as pointed out in the appended claims.

In the accompanying drawingsFigure I is a general plan of a system involving in combination a feed water heater, an elevated storage tank, and means for regulating the temperature of the water in said storage tank; also a boiler feed pump and details of connections which complete the system hereinafter more fully described. Fig. II is a plan view of a service pump which receives water from the storage tank, and delivers it at a reduced temperature under pressure, to locomotive boilers for cleaning or other points of use. Fig. III is a modification, showing the use of but one pump, which serves the purpose of conveying Water to the storage tank, or direct to other point of use. Fig. IV is a further modification showing a feed water heater in com- Speciflcation of Letters Patent.

bination with two pumps and an elevated storage tank, with means for maintaining water at a uniform temperature'within the storage tank, one pump supplying the tank, and the other pump for supplying the boilers or other point of use. F1g.V is a further modification showing the combination of a feed water heater and storage tank, and connections for supplying by gravity, water thereto; a pump and means for conveying the exhaust steam from said pump to the heater. Figs. VI and VII are details respectively of the means employed for reducing the temperature of the water received from the storage tank, as shown in Fig. II.

Referring to Fig. I,I employ a feed water heater l of a well-known open type, in which the water is brought in contact with the exhaust from engines or generating units (not shown), being introduced into the heater through a suitable lead or pipe 2. It is manifest, however, that the exhaust steam may be supplemented automatically with live steam to cover such periods when the available exhaust steam is insufficient to heat the total amount of water required, as shown particularly in Figs. III and V.

While I have described a heater of the open type, I would have it understood that I am not limiting myself to this particular type of heater. On the contrary, any type of heater may be advantageously used in the system forming the subject matter of this invention without departing therefrom.

3 indicates a cold water main which may, if desired, supply the water to the heater directly through leads or pipes 4 and 5, controlled by float actuated valve -5; the pipe -5- being arranged to discharge at a point in proximity to the top thereof so that the water will be distributed over the heater trays, as is well-known and therefore not shown, or when air compressors, heating coils or similar devices are employed, the water may be discharged therefrom and fed directly into the heater, in which event the piping arrangement for accomplishing this I have indicated at 678 and 8 The supply pipe -4 is elongated to afford an overflow path for the water from the main 3; the length of the pipe being governed by the amount of pressure carried in the heating system and friction in the pipes. The upper end of pipe 4 discharges into a pipe connection with the sewer. 9 indicates the main exhaust for the heater l, having located therein the back-pressure valve 10-. To the main exhaust 9 may be connected suitable piping communicating with a heating system; the lead or pipe ll forming the induct to the heating system (not shown), while 12 indicates the educt, which is water sealed, through which is communicated the returns from the heating system to the feed water heater.

The connections for this heating system just described may be incorporated in the system as shown or may be dispensed with if desired.

13- is a suitable valve seated in the pipe 1l for admitting or cutting off supply to the heating system. Immediately above the back-pressure valve -10 of the main exhaust 9 and communicating with the feed water heater I provide a water sealed drip pipe 1l.

15 indicates a boiler feed pump which delivers the hot water received from the heater l through suitable piping 16'17 and 18 to the stationary boilers (not shown). The delivery of the Water to the stationary boilers is insured by having the pump supply pipe 16- opening at a lower point on the heater than the opening 15, through which the hot water is to be conveyed to a pump or other means which is to elevate or to flow hot water to a storage tank, hereinafter described.

I do not wish to be limited to the use of an elevated storage tank. It may be advantageous in some instances to use a storage tank on the same level with or below the heater, such as, for instance, shown in Fig. V, in which event I eliminate the use of the pump needed to force the water to the tank when elevated above the heater. However, I preferably use an elevated storage tank for the reason that I am thereby enabled to maintain the stored water at a given temperature by providing the circulating means hereafter fully described.

19 is a thermometer located above the lead or pipe. 16 to indicate the temperature of the water being fed to the stationary boilers. For storing a supply ofhot water for filling, testing or washing locomotive boilers, a tank -20 is employed. This tank is usually provided with a vent 21 and glass gage 22 for preventing air logging of tank and indicating the quantity of water in the storage tank.

For forcing the hot water from the heater -1 to the elevated storage tank 20- I employ a pump -23 to which is connected, as shown, the leads or pipes Q4 and 25 which form the path for the water from the heater to the tank. The water when it leaves the heater 1, it will be understood, is at a high temperature, approximately 210 F therefore, to insure the maintenance of the stored water within the tank at a proper uniform temperature, I provide means for carrying it back to the heater to be reheated when the water reaches a fixed level in the tank. This I accomplish by especially providing pipe or lead 26-- which is connected within the storage tank 20- to a vertically arranged pipe 26* open at either end, the upper end extending above the water line. This arrangement insures the return of water to the heater from the lowest strata within the tank, and, therefore, that which is the coldest and which it is desired to reheat. The other end of pipe 26 is water sealed and connected to the heater 1 at a point near the top thereof, preferably 01)- posite the cold water inlet. From this arrangement, it will be seen that the water of the lowest temperature in the storage tank is permitted to return to the heater 1 where it is reheated, whereupon it is again forced back into the storage tank 20 by means of -a pump 23. Through this continuous circulation, I maintain hot water in the storage tank at a substantially uniform temperature.

It is apparent that the hot water from the heater may be arranged to discharge direct from heater through lead or pipe 24z to pump -2-l (see Fig. II), thence to locomotive boilers or other points of use and not from the storage tank 20 as described.

Valves 27 and 28 are located in the leads or pipes 4 and 16- which regulate the admission of cold water to the heater 1 and pump 15, when desired, from the water main 3.

Leading from the storage tank 20- is a pipe -29 which is connected with pipe 30 through which the water from the storage tank 20is led to the locomotive boilers (or other points of use not shown). The pipe 30 is connected with a pipe 31 which communicates with a sewer pipe indicated at 32-. A gate valve -33 is provided in pipe 30 for permitting the water from the tank 20 to be drawn off into the sewer through the pipe 31. It will be observed that the water is drawn from storage tank 20 through pipes 29 and -30 which provide a gravity distribution to the locomotive boilers or other points of use. It is manifest, however, that I may connect a pump'to the lead or pipe 30 for the purpose of receiving the water and dischargingit at a rapid rate into the locomotive boilers, or to other points of use, as shown in Fig. II.

For the purposes of washing or testingthe locomotiveboilers and for other uses, I provide means for reducing the temperature of the water drawn from the storage tank As the water in the storage tank -2() is at a high temperature approximately 210 F.it is necessary, in order to utilize this water for the purposes of wash ing and testing locomotive boilers, to reduce the temperature of it so as to prevent the possibility of scalding the workmen engaged in this work. For this purpose, the temperature of the water is sometimes reduced to 125 F. I will now proceed to describe the manner in which I effect the lowering of temperature of the water for this service :-In Fig. II, a suitable pump -24t is provided and has communication with the elevated storage tank -20 through pipes 293,0 and --30*-. The pump -Q4e is also connected with the cold water main 3- through pipe ,--30. Suitable check valves 31 and 81 are provided in pipes 30 and 30" to prevent the water entering the cylinder of the pump S4E being forced back through the pipes "O- and 30 thus confining its discharge through pipe -32 to the locomotive boilers or other points of use. A gate valve 35- is provided in pipe 30 for the purpose of directing and controlling the flow of the water from the storage tank 20-. A similar gate valve 35 is provided in pipe 30 for cutting off the pump when necessary. The hot water enters the cylinder of the pump -24 through pipe -30 and the cold water through pipe -30" from the cold water main -3. In the pipe -30" (see also Fig. VI) I provide a diaphragm controlling valve 32 I also provide an automatic hot water regulator -83 Fig. VII, which is situated in pipe 32, having communi-. cation with the pump cylinder. This hot water regulator regulates the temperature of the water being fed from pump 24 through pipe 32 to the locomotive boilers or other points of use. I provide a pressure water pipe 33, in suitable connection with any source of water pressure, not shown, connecting the hot water regulator 33 with the diaphragm controlling valve -32---. In the pipe -33 is located a drip connection 36.

The hot water from the elevated storage tank enters the pump cylinder through pipe 30'*-, and the cold water from cold water main 3 through pipe 30 and diaphragm controlling valve -32', located therein. From the pump cylinder the water, the temperature of which has been reduced through the admixture of the two waters just described, is forced through pipe -32 into and through the hot water regulator 33. Within the hot water regulator 33 is located a thermostatic device or tube -33 which lengthens by expansion as the temperature of the water being fed therethrough rises (see Fig. VII) carrying with it rod 38 and causing valve 38* to open, which allows the water pressure connected to and passing through pipe 33 and filling space -33 to flow through pipes 33 and -33 to diaphragm valve 32 (see Figs. II and VI). The pressure of the water on the diaphragm serves to open the valve 33 and admit more cold water from cold water main -3 through pipe 30 to be mixed with the supply of hot water entering the pump cylinder through pipe 30 When sufficient water has been admitted to cool the water to the proper temperature, the tube 33- contracts causing the valve 33 to close, thereby shutting ofi? the water pressure from diaphragm of the valve 32, and as the drip valve 36 is always slightly open, the pressure on the diaphragm is reduced, thereby permitting the spring 33 to close the valve -33 and cut off or reduce the supply ofcold water to the pump cylinder. It will be readily understood from this that the valve 33 is under the direct control of the thermostatic pipe 33 and that only the required amount of water will be admitted through the valve to maintain the desired temperature at the outflow to the point or points of use.

A thermometer 34: is located on pipe 32" for indicating the temperature of water issuing from the pump cylinder.

It is readily understood that the automatic hot water regulator can be adjusted to vary the temperature of the water to any desired degree. To accomplish this adjustment a dial or index is provided on the surface -33 and a pointer 33 on the rotating spindle -33 By rotating this spindle, the port 33- is moved longitu dinally into and out of registry with the port 33-, thus diminishing or increasing the amount of pressure admitted to the diaphragm valve 32 The rotation of the spindle also either increases or shortens the thermostatic rod 33 thus causing the valve -33* to operate at the temperature desired.

It is apparent that I need not necessarily take the water from the elevated storage tank as described, but may take it directly from the heater and deliver it into the cylinder of the pump 24 (see Figs. I and II). To accomplish this I provide a connection -2P connecting pipe -24 with pipe -30 A valve 16" is provided in pipe 24t for controlling the passage of water therethrough.

The operation of the pump -2 l'"* is automatic; control being established by means of a pump governor 36. For example, when one of the nozzles or valves (not shown) on the supply pipe 82 to point of discharge to the locomotive boilers or other points is open, the pump governor immediately starts the pump which is actuated by steam from any suitable source through lead or pipe 87.

Referring now 111 detail to Fig. III,--I illustrate a modification of the system, wherein the boiler feed pump 15 is employed for elevating the water to the storage tank or, when desired, to deliver the water at a rapid rate directly to the boilers. To accomplish this, I connect a pipe -18 to pipe IS. A valve --18" is located inpipe 1S for the purpose of manually controlling the direction of flow of water delivered from the boiler. feed pump 15-. 19* indicates the water relief valve, and 19" the pipe discharging into the storage tank 2O. 20* indicates an overflow opening in storage tank 20. 20 indicates a discharge pipe through which the water is distributed to washing or drying. machines or other points of use. The

exhaust from pump 15 is conveyed or delivered to the heater through pipes 21*, 2l and pipe -2-. 16 inclicates a valve in pipes l6 and 17 leading to the pump 15.

It may be advantageous to supplement the exhaust from both engines and pumps by a supply of live steam when the exhaust is not found sufiicient to heat the feed water to the degree required.

22 indicates the pipe through which the supplementary live steam may be delivered to the heater. In this pipe is located the pressure reducing valve indicated at 22"- for an obvious purpose.

2. indicates a drain or waste pipe connected with the lower portion of the heater 1-.

Referring now in detail to Fig. IV, I employ two pumps similar to the system illustrated in Fig. I. It will be noted that in both instances the boiler feed pump communicates with the heater at a lower point in the heater than the pump 23-, which elevates the water to the storage tank 20. This is important for the reason that it is absolutely necessary that the boilers have sufficient water; hence, with this arrangement, this service will always be assured of a supply. 23" and 23 indicate manually operated stop valves in pipes 17- and 26. Stop valve 23" is employed for the purpose of cutting off the boiler feed pump; 23 for the purpose of cutting off the return of the Water from the storage tank 20 to the heater. It will be further noted that the water in the storage tank 20 is maintained at a given temperature, as a similar circulating means is here employed, thereturns being taken from the' lower strata within the tank -20'- through pipes 26 and -26 to heater -1. The gravity distribution of the hot water from tank 20 is made from pipe n() in which is situated a stop valve 2 P.

As before stated, the storage tank may be situated on a level with the heater (see Fig; V), and in which event the Water is supplied to the tank 20 from the heater 1 through pipe 25.

25 and -25 indicate respectively suitable check and gate valve in pipe 25.

21 indicates a manually operated valve in the pump exhaust pipe 2l 21 indicates a similar valve in the feed water pipe l7 to the pump 15.

It is obvious that various changes may be effected in the construction and arrangement of the piping and other elements of the systems herein described without departing from the spirit and scope of the invention.
